The article adopted a new filtering-cloud composing technology used to monitoring drought,analyzed the property of Ts—NDVI characteristic space and the TVDI's indicating drought ability, put forward the TVDI compute model, grade standard, and the impact estimation method. The result indicated: 1 the decade-composed data obtained by the maximum surface temperature principle has better ability than the composed data obtained by the maximum NDVI on monitoring drought; 2 in the Ts-NDVI characteristic space,the dry side and the wet side almost are horizontal lines when the NDVI is on the small side, the temperature difference is about 45℃; 3 the TVDI has inequable level on monitoring drought as its value, the less TVDI indicates without drought occurrence, the bigger TVDI shows the drought certainly happened, the unsure drought conclusion mainly comes from the middle TVDI; 4 the monitored results of Sichuan hot-drought in 2006, obtained by the remote sensing and by the climate index, are basically consistent, the estimating error on the bearing drought crop area and on the drinking trouble population is within 10%.
采用了干旱监测合成滤云新技术,分析了Ts—NDVI特征空间属性和TVDI指数干旱监测能力,提出了四川伏旱TVDI计算模型、分级标准、和影响评估方法,结果表明:1按最大地表温度原则得到的旬合成数据比按最大植被指数原则得到的旬合成数据具有更强的旱情监测能力;2在Ts—NDVI特征空间中当NDVI较小时干湿边几乎同为水平直线,两者相差约45℃;3TVDI指数因其大小不同而对旱情的监测能力也不一样,较小时说明没有干旱发生,较大时则一定有干旱发生,中间段对干旱的监测具有不确定性;42006年四川伏旱遥感监测与气候监测结果基本一致,农作物受旱面积与饮水困难人口数估算误差在10%以内。

It shows that the critical exponents of conductivity, u, are in good agreement with the mean-field percolation value and in clear disagreement with the universal value in three dimension. This nonuniversal behavior can be interpreted as a result of the interaction between CB and polymer. The influences of the property and volume fraction of CB and radiation crosslinking on conductivity and critical exponent were also studied.

Methods 120 SD rats were divided randomly into blank group, model group, Baoliezhi control group and Qianliening granule groups with different doses. The models were established with hypodermic injection of testosterone propionate at 4 mg/kg after orchiectomy, at the same time, these rats were gastric perfused with different drugs respectively for 30 days. The body weight, prostate weight, prostate index, morphological changes, the level of T and E2 were measured. Results The body weight in model group was significantly lower than that in control group (P.05), the prostate weight and index were obviously higher than that in control group (P.01). The prostate weight and index were decreased significantly in Qianliening granule groups with meddle and high doses (P.01), the level of testosterone was increased significantly and E2 was decreased obviously in Qianliening granule group with high doses.

The critical nitrogen content in heading period was used to calculate the biggest accumulation quantity of nitrogen. The latent distribution index of leaf and stem, which was the variety heredity parameter, were used to distinguish the difference in nitrogen assignment in different varieties. The dynamic content of the nitrogen accumulation before anthesis could be described with a Richards model. The dynamic content of the nitrogen remobilization in leaf with leaf area index could be described with a power model, and the nitrogen absorption of grain from soil with dry weight could be described with a power model. The dynamic content of nitrogen density in stem and spike with physiological development time could be described with a nonlinear model.

The distribution database and the geographic cladograms of the superfamily was set up. The distribution pattern of the superfamily was concluded and the origination centre of the superfamily was also discussed. We deduced that the South Asia is probably the origination centre of the superfamily. Two new index for zoogeographic analysis, index of high taxa distribution and the possibility index of the origination of a high taxa, were proposed.

The test groups were drenched orally with different dosages of compound Radix scutellariae granules. After being drenched orally for ten days, their thymus-index and spleen-nidex, immune globulins of IgA, IgG, IgM and alexins of C3, C4 of serum were defermined, and experiments in vivo were done. The mice-spleen's lymphocytes which were cultured in vivo were added with different concentrations of compound Radix scutellariae granules. The lymphocytes translation stimulate indexes were measured. The ability of licking up neutral red of the peritoneal macrophages cultured in vivo was measured in the groups.
